Using a Zero-Latency Limiter to Boost Your Livestream Audio

If you’re livestreaming video and audio, your audio should be sent out to the stream at a nice loud level. If your mic’s level is too low, it may be difficult for viewers to hear you.

I recently tried using the Fabfilter Pro-L 2 to boost my outgoing livestream audio. Fabfilter’s support suggested this: “If you need minimum latency, choose the Transparent algorithm and also disable True Peak Limiting in the bottom bar.”

Then I tried using Fabfilter Pro-MB for the same purpose. And Fabfilter’s support suggested this: “Do you want to use zero-latency processing? Disable oversampling and lookahead in the bottom bar, and use either Dynamic Phase or Minimum Phase processing.”

Each of those 2 plugins seemed to create a tiny bit of latency, but I didn’t have time to verify that technically.

Ultimately I decided not to use any plugins to boost my outgoing audio level. I simply boosted the audio level in Audio Hijack, which nicely limits any peaks that go above zero 😉

And viewers remarked that that sounded better.

Do you have any ideas or tricks about livestream audio?
